I have a degree in physics. I taught for a while, and made enough through investing that I can now afford to be a full-time student again. I like companies that make profits by making useful things, e.g. solar, commodities, telecommunications. Companies that make money through advertising, intellectual property, or financial engineering are, in my opinion, trying to profit by winning a zero-sum game - no better than con-men.
